So , if your truck ready was a show winner you’d have60k or more in it - and you’d have a real problem on your hands right now , a very costly problem.

I agree with your call to work with what you already have. Get that mating of parts properly repaired the you know what you have. I trust the shop will pressure test the tank for you?
